EU active substance expiry date postponed

Active substance expiry date postponed whilst the renewal evaluation is completed in the EU

For reasons beyond the control of the applicant, the approval of the active substance/product type combination listed below was likely to expire before a decision could be taken on its renewal under the EU BPR.


To allow sufficient time for the renewal evaluation to be completed, a decision has been taken to postpone the expiry of the approval until the following date. This affects NI:

If you want to supply new biocidal products containing this active substance, you can still apply for EU BPR product authorisation.


New products (including new trade names) must not be supplied in NI until product authorisation is granted.


HSE will provide a separate update on the renewal decision when relevant.
